Hi Anderson,
we don't anticipate having the GPUs be required ever at this point.
cheers,

Yes, Pedro, this is the idea.
We have been using FreeSurfer in a cluster, but in that setting, every node
have their own graphics card (like I think you have at USP). For the new
system, however, the blades don't even have PCI or AGP expansion slots, so to
display, now that we know that GPUs at the moment are not compulsory for FS,
we may then plan to connect using separate nodes.
I have another question though, about the GPU processing that the developers
are looking forward to: any idea on when GPU might become a requirement, or
how essential it might become?
That's because what is going to a brand new system may quickly become
obsolete for FreeSurfer if the GPU stuff comes along soon.
Thanks a lot!

Hi Anderson,
I don't remember if I showed you here in Sao Paulo our Freesurfer
processing.
I think you could have a cluster or for better power consumption a Blade
Server to run several recon-all at same time (don't forget to reserve at
least 1GB Ram per core)
To visualize your data you can use a normal Linux workstation with Nvidia
or ATI GPU.
As Bruce told you the GPU issue is something the FreeSurfer community want
but it's not so easy to implement in this situation.
Best Regards,
Pedro Paulo Jr.

Dear all,
We are considering to buy a blade system, and FreeSurfer would be
one of the applications to run on it. We know that a 3D graphics
card, with support for OpenGL and built-in memory+GPU, is
recommended. What we are not sure is whether it is mandatory for
all the FreeSurfer routines, of if that is necessary only to
render data in the screen, in particular, with tksurfer.
If it is used only for display purposes, and not for real
processing, then we may consider having graphics card only in a
few separate nodes, that the users could access with an X-server
(or maybe VNC with OpenGL support).
Does it all makes sense, or do all and every computer must have
their own 3D card for everything?
Thanks in advance!
Anderson
